Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical head and a magnetic head which are interlocked with each other with a magneto-optical recording medium in between so as to face each other. The present invention relates to a magneto-optical recording device.

[0002]

2. Description of the Related Art A conventional magneto-optical recording device is shown in FIG. In this magneto-optical recording apparatus, a magneto-optical recording medium (hereinafter, referred to as a magneto-optical disk) 53 attached to a motor shaft 52 of a spindle motor 51 is sandwiched between the optical system heads 54.
And the magnetic head 55 are arranged so as to face each other.

The optical system head 54 deflects the laser light L emitted in the horizontal direction from a laser light source (not shown) in the vertical direction (to the side of the magneto-optical disk 53) by the prism 56, and the deflected laser light L is used as a lens. Magneto-optical disk 53 at 57
The recording layer (perpendicular magnetization film) 58 is focused.

On the other hand, the magnetic head 55 has a central magnetic pole core 5
9 and a side magnetic pole core 60 provided so as to surround the central magnetic pole core 59 are integrally formed of ferrite, and a coil 61 is inserted into a space formed between the central magnetic pole core 59 and the lateral magnetic pole core 60. It is configured. A distance sensor 62 is attached to the tip of the magnetic head 55, and an actuator 64 is attached to the rear of the distance sensor 62 via a gimbal spring 63.

The optical system head 54 is slidable in the track direction of the magneto-optical disk 53 by a slide mechanism 65, and the movement of the optical system head 54 is transmitted to the magnetic head 55 via an interlocking mechanism 66. By
The optical system head 54 and the magnetic head 55 are configured to face each other and work together.

When writing information to the magneto-optical disk 53, the magneto-optical disk 53 is used as the motor shaft 52.
Laser beam L from the optical system head 54 in a state where an external magnetic field is applied by the magnetic head 55 to the recording layer 58 formed on the magneto-optical disk 53. Then, in the recording layer 58, the portion receiving the incidence of the laser light L performs the magnetization direction according to the direction of the external magnetic field as the temperature of the laser light L increases.

Then, when the laser light L has a substantially constant light intensity, a so-called magnetic field modulation method in which the external magnetic field changes according to a recording signal is used to form a magnetization direction reversal region with a predetermined pattern in the recording layer 58. Once formed, information is written.

The distance sensor 62 and the actuator 6
4 is a case where the distance sensor 62 detects a displacement between the magnetic head 55 and the surface of the magneto-optical disk 53, and the actuator 64 is driven based on the detected output, so that the magneto-optical disk 53 causes surface wobbling during its rotation. Also in the above, the distance between the magnetic head 55 and the surface of the magneto-optical disk 53 can be maintained at a predetermined value.

[0009]

However, in the conventional magneto-optical recording apparatus, even when the magneto-optical disk 53 causes surface wobbling during its rotation, the gap between the magnetic head 55 and the surface of the magneto-optical disk 53 is set to a predetermined value. In order to maintain the value, it is necessary to provide the magnetic head 55 with the distance sensor 62, the actuator 64, and the like, which complicates the configuration of the apparatus itself and increases the size.

Further, in this case, there is a problem that an excessive driving load is applied to the actuator 64. Moreover, when the distance sensor 62 is composed of capacitance detecting electrodes, an eddy current is generated due to the magnetic field from the magnetic head 55, and the capacitance detecting electrodes may generate heat due to eddy current loss.

On the other hand, as shown in FIG. 9, a method of arranging the magnetic head 53 on the optical system head 54 side has been proposed. In this case, the "optical path" of the optical system head 54 is proposed.
Since the "magnetic path" of the magnetic head 55 overlaps with that of the magnetic head 55, it is necessary to devise an optical path hole 67 at the center of the magnetic head 55.

The magnetic head 55 is an optical system head 54.
Since it is arranged on the back surface side of the substrate (transparent substrate made of polycarbonate) of the magneto-optical disk 53,
To increase the distance between the recording layer (perpendicular magnetization film) 58 formed on the upper surface of the substrate and the magnetic pole of the magnetic head, and to effectively reach the position of the recording layer 58 with the magnetic field, the magnetic head 55 is used.
Magnetic pole (for example, central magnetic pole core 59) and exciting coil 61
Must be large.

This is a factor that deteriorates the magnetic head characteristics such as an increase in the inductance and resistance of the magnetic head 55 and a decrease in the magnetic field. Especially in the high frequency range (10 MHz
For the magnetic head for magneto-optical recording used in the above), small size and low inductance are essential conditions, but the result is contrary to this.

As described above, in the conventional magneto-optical recording apparatus, the servo mechanism having a complicated structure is required, and the magnetic head 55 itself needs to be increased in size. Therefore, there was a limit to the reduction of manufacturing cost.

The present invention has been made in view of the above problems, and an object of the present invention is to eliminate the need for a servo mechanism having a complicated structure, to reduce the size of the magnetic head, and to provide the apparatus itself. An object of the present invention is to provide a magneto-optical recording device that can be made compact and lightweight and can be manufactured at low cost.

[0016]

At this time, the interlocking mechanism 3 and the magnetic head 9 mounted in the cartridge 5 are mechanically and electrically connected to each other, and the magnetic head 9 is arranged at a position facing the optical system head 2. Constitute.

Further, in the magneto-optical recording apparatus of the present invention, the cartridge 5 containing the magneto-optical recording medium 7 and the exciting coil 17 are attached to the portion other than the light emitting area and are formed on one side of the cartridge 5. The optical system head 2 with the exciting coil 17 for irradiating the magneto-optical recording medium 7 with the light L through the window 8 and the optical system head 2 with the exciting coil 17 in the track direction of the magneto-optical recording medium 7. The optical system slide mechanism 25 for sliding and the slide mechanism 10 provided on the other side of the cartridge 5 are attached,
The magnetic core 15 slidable in the track direction of the magneto-optical recording medium 7, the optical system head 2 with the exciting coil 17 and the magnetic core 15 are interlocked with each other to slide in the track direction of the magneto-optical recording medium 7.

It is arranged so as to be arranged at a position opposed to the optical system head 2 with 7.

[0018]

According to the first configuration of the present invention described above, since the magnetic head 9 is attached to the cartridge 5 containing the magneto-optical recording medium 7 via the slide mechanism 10, The facing dimension accuracy of the magnetic head 9 can be improved, and the distance between the center magnetic poles of the magneto-optical recording medium 7 and the magnetic head 9 can be narrowed.

Therefore, even if the magnetic head 9 is downsized, the magnetic field from the magnetic head 9 can effectively reach the recording layer (perpendicular magnetization film) 22 of the magneto-optical recording medium 7. Therefore, a small magnetic pole and exciting coil 17 can be used as the magnetic head 9, and a magnetic field required for magneto-optical recording can be applied with a small magnetomotive force, low inductance and low loss. Also, since the facing dimension accuracy is improved,
Since the focusing servo mechanism (distance sensor, actuator, etc.) dedicated to the magnetic head is not required, it is possible to reduce the size and weight of the apparatus itself and the manufacturing cost.

Further, since the magnetic head 9 is attached to the cartridge 5 and the cartridge 5 is detachable from the magneto-optical recording device, the magneto-optical recording device is an optical device except for the interlocking mechanism 3.

There is.

On the other hand, the optical system head 2 in the apparatus body 4 is
After the cartridge 5 is mounted, it is energized to irradiate the recording layer (perpendicular magnetization film) 22 of the magneto-optical disk 7 with the laser light L from a laser light source (not shown) through the window 8 of the cartridge 5. That is, the laser light L emitted from the laser light source in the horizontal direction is deflected in the vertical direction (on the side of the magneto-optical disk 7) by the prism 23, and the deflected laser light L is recorded on the magneto-optical disk 7 by the lens 24. Layer 22
It is configured to focus light on the top. The optical system head 2 is slidable in the track direction of the magneto-optical disk 7 by a known slide mechanism 25.

The interlocking mechanism 3 is connected to the slide mechanism 25 of the optical system head 2. In principle, the interlocking mechanism 3 is composed of a U-shaped interlocking arm 26 extending upward so as to avoid the accommodation space of the cartridge 5, and when the cartridge 5 is mounted, the upper end of the interlocking arm 26 and the magnetic head 9 are connected to each other. Are configured to be electrically and mechanically connected. The upper arm 26a of the interlocking arm 26 is formed in a leaf spring shape.

That is, as shown in one example in FIGS. 2 and 3, first, in the initial state (see FIG. 3A), the interlocking arm 26 is urged upward by an L-shaped interlocking control rod 27, for example. Although the upper arm 26a is located above, the interlocking control rod 27 is attached as the cartridge 5 is mounted.
Moves downward, and the movement causes the upper arm 26a to move downward.

When the cartridge 5 is mounted, the magnetic head 9
Is fixed (biased) to a predetermined position by the compression spring 13, so that the interlocking arm 26 is positioned on the fixed position of the magnetic head 9 by the position control of the interlocking control rod 27. Then, as described above, the upper arm 2 is moved by the downward movement of the interlocking arm 26 by the interlocking control rod 27.
The lower surface of the tip of 6a contacts the head base 12 on the magnetic head 9.

Here, the lead extending from the exciting coil 17 of the magnetic head 9 is electrically connected to the terminal 18 formed on the upper surface of the head base 12, and a recess is formed in the central portion of the upper surface of the head base 12. 28 is formed. On the other hand, a wiring 29 extending from a head drive amplifier (not shown) is formed on the inner side surface of the interlocking arm 26, and the wiring 29 terminates at a pressure contact connector 30 formed on the lower surface of the tip of the upper arm 26a.

The upper arm 26a and the magnetic head 9 are mechanically connected by
And the pressure contact connector 30 are electrically connected, and the signal from the head drive amplifier is supplied to the exciting coil 17 of the magnetic head 9 through the wiring 29, the pressure contact connector 30 and the terminal 18.

Further, since the interlocking arm 26 and the magnetic head 9 are mechanically connected, the optical system head 2 and the magnetic head 9 are mutually moved by the movement of the interlocking control rod 27 in the track direction of the magneto-optical disk 7. In conjunction with this, it moves in the track direction.

In FIG. 2, reference numeral 32 denotes a shutter,
Normally (when not in use), the magnetic head 9 is blindfolded from the outside, and when the cartridge 5 is attached to the apparatus main body, the shutter 32 slides laterally to expose the magnetic head 9 to the outside. Is. With this shutter 32, the cartridge 5 for dust and dirt when not in use
It is possible to prevent mixing into the inside. The shutter 32 may be attached to the window 8 side of the cartridge 5.

When writing information to the magneto-optical disk 7 in the cartridge 5, the magneto-optical disk 7 is rotated at a predetermined rotation speed via the motor shaft 19, and the magneto-optical disk 7 is further recorded. In a state where an external magnetic field is applied to the layer 22 by the magnetic head 9, the optical system head 2
When the laser beam L is incident on the recording layer 22, the portion of the recording layer 22 that receives the laser beam L performs a magnetization direction according to the direction of the external magnetic field as the temperature of the laser beam L increases.

The so-called magnetic field modulation method in which the external magnetic field changes according to the recording signal when the laser light L has a substantially constant light intensity is obtained, and the magnetization direction reversal region is formed in the recording layer 22 with a predetermined pattern. Once formed, information is written.

According to the first embodiment, since the magnetic head 9 is attached to the cartridge 5 containing the magneto-optical disk 7 through the slide mechanism 10, the opposing dimension of the magneto-optical disk 7 and the magnetic head 9 is determined. The accuracy can be improved, and the distance between the surface of the magneto-optical disk 7 and the central magnetic pole core 15 of the magnetic head 9 can be reduced.

Therefore, even if the magnetic head 9 is downsized, the magnetic field from the magnetic head 9 can effectively reach the recording layer 22 of the magneto-optical disk 7. Therefore, a small magnetic pole can be used as the magnetic head 9, and a magnetic field required for magneto-optical recording can be applied with a small magnetomotive force, low inductance, and low loss. Further, since the facing dimension accuracy is improved, the focusing servo mechanism (distance sensor, actuator, etc.) dedicated to the magnetic head is not required, so that the size and weight of the apparatus itself and the manufacturing cost can be reduced.

Further, since the magnetic head 9 is attached to the cartridge 5 and the cartridge 5 is detachable from the magneto-optical recording apparatus main body 4, as the magneto-optical recording apparatus, the interlocking mechanism 3 is excluded. The optical system can be configured only, and the structure of the device itself can be simplified.

Further, "optical modulation type magneto-optical recording device",
"WO (write once) type device", "CD and LD" and other drive devices can be handled in a similar manner,
In particular, a magnetic field modulation type magneto-optical recording apparatus can be constructed by directly using a “CD or LD” drive apparatus that has been proven in the past, so that the practical application of the magneto-optical recording apparatus can be promoted.

Next, some modifications of the magneto-optical recording apparatus according to the first embodiment will be described with reference to FIGS. 4 and 5. The same reference numerals are given to those corresponding to FIG.

The first modification shown in FIG. 4 has substantially the same structure as the first embodiment, except that a sliding member 41 is provided on the surface of the magnetic head 9 facing the magneto-optical disk 7. different. In this example, unlike the first embodiment, magneto-optical recording is performed while the magnetic head 9 slides on the magneto-optical disk 7 via the sliding member 41. Therefore, as the sliding member 41, a material having wear resistance and small sliding resistance (small friction coefficient), for example, a resin material having an ultra-high molecular structure (molecular weight of about 2,000,000) is used. In this example, Hi-Zex MILLIO manufactured by Mitsui Petrochemical Co., Ltd.
N (trade name) was used.

Next, a second modification shown in FIG. 5 is an example in which a slider 42 is provided on the side surface of the magnetic head 9 and the magnetic head 9 and the head base 12 are connected by a gimbal spring 43. According to this configuration, like the hard disk, the magnetic head 9 is levitated in the air to perform magneto-optical recording.

Only the central magnetic pole core 15 is attached to the slide mechanism 10 via the core holder 44. in this case,
Since the exciting coil 17 is provided on the optical system head 2 side, it is not necessary to form electrical wiring on the interlocking arm 26, and the lower end of the upper arm 26 is inserted into the recess 45 formed on the upper surface of the core holder 44. It suffices to provide only the connecting pin 31 to be used. In the figure, the magnetic flux is shown by a chain line.

According to the second embodiment, the optical system head 2
Since the exciting coil 17 is attached to the side, and the central magnetic pole core 15 is attached to the cartridge 5 containing the magneto-optical disk 7 via the slide mechanism 10, the facing dimension accuracy of the magneto-optical disk 7 and the magnetic head 9 is improved. The distance between the magneto-optical disk 7 and the central magnetic pole core 15 can be reduced.

From this fact, even if the central magnetic pole core 15 is downsized, the magnetic field from the exciting coil 17 is applied to the magneto-optical disk 7.
The recording layer 22 can be effectively reached. Therefore, a small central magnetic pole core 15 can be used, and a magnetic field required for magneto-optical recording can be applied with a small magnetomotive force, low inductance and low loss. Further, since the facing dimension accuracy is improved, the focusing servo mechanism (distance sensor, actuator, etc.) dedicated to the magnetic head is not required, so that the size and weight of the apparatus itself and the manufacturing cost can be reduced.

Further, the central magnetic pole core 15 is the cartridge 5
Since the cartridge 5 is attached to the magneto-optical recording apparatus main body 4 and is detachable from the magneto-optical recording apparatus main body 4, only the optical system 2 with the exciting coil 17 is used as the magneto-optical recording apparatus except the interlocking mechanism 3. It can be configured, and simplification of the structure of the device itself can be achieved.

Further, "optical modulation type magneto-optical recording device",
"WO (write once) type device", "CD and LD" and other drive devices can be handled in a similar manner,
In particular, a magnetic field modulation type magneto-optical recording apparatus can be constructed by directly using a “CD or LD” drive apparatus that has been proven in the past, so that the practical application of the magneto-optical recording apparatus can be promoted.

In particular, according to the second embodiment, since it is not necessary to provide electrical wiring to the interlocking arm 26, the structure of the interlocking mechanism 3 can be simplified, the device itself can be made smaller and lighter, and the manufacturing cost can be reduced. The cost reduction can be further promoted.

In the second embodiment, only the central magnetic pole core 15 of the magnetic head is attached to the cartridge 5. However, as shown in FIG. 7A, the central magnetic pole core 15 is integrally formed with the base core 14. 7B may be attached, or as shown in FIG. 7B, a central magnetic pole core 15 is provided in the central portion of the base core 14, and the central magnetic pole core 1 is provided.
A ring-shaped side pole core 16 may be attached so as to surround 5.

Other types of recording media such as write once type (or write-once type) optical recording medium, phase change type repetitive optical recording medium, reflectance change type read-only recording medium, etc. The magnetic core portion (the magnetic head 9 or the central magnetic pole core 15) built in is omitted, and the interlocking mechanism 3 on the apparatus main body 4 side is disabled, and the Kerr effect reading and the light intensity change reading are both performed by the optical system head 2. By providing a function and a function of adjusting the laser power at the time of recording and reproducing, reproduction and recording of each recording medium can be shared by the same mechanism.
